A well written script is the cornerstone of any great on hold message. It must capture the caller’s attention, so they remain engaged while navigating menu options or waiting on hold. The script that callers hear can set the tone for the rest of the conversation. It should also be in line with your goals, which can be broken down to 3 main objectives. It can be to inform the caller, promote the brand or product, or just entertain the caller. Most of all, it has to be engaging.
Let’s face it, customers who call to a business don’t want to be on-hold. The best on hold message is no hold at all!

If it is a genre, hold music, it's fair to say, is a troubled one with few hits. It's not really meant to be loved or even listened to — it's meant to communicate something specific: Don't hang up. (Cornell makes this plea specifically at the end of his song.) Silence is believed to be a death knell for phone calls — people will simply think the line is dead and hang up. This is true even on non-hold calls; it's why phone companies transmit something called a "comfort tone" over phone lines, a barely audible synthetic noise that signals a connection is still there.
